GASM was built 3 feet taller than Shockwave and the profile going into the midcourse brake run was a little different so that the turn wasn't so powerful

Shane,

Viper's layout was much improved in a way that removed the sharp turn going into the brake run. After the two loops that are now parallel to the lift, you hopped straight up into the mid course.

Brett,

After Shockwave was announced to be taken down, it was early said by Six Flags that it would operate at another park in the future. With that in mind a poster no longer with us (RIP: Mamoosh) posted that he had it on good authority that the ride was being split , the two halves were going to two different parks with some track work done to give it a complete circuit. Thus was born "Shock" and "Wave" Some people couldn't take a joke I guess. But it was pretty funny.

The ride sat neatly in pieces at Great America until it was scrapped sometime in 2004.
